No problems here.  I've had mine for about 3 months now and have about 23 hours.  Up until the last couple of nights I mainly just mowed with it and it mows great.  I put about 5 hours of loader work on it the last couple of nights moving dirt at a neighbor's house.  It seemed to have plenty of power, but I am lacking in traction.  This is because I have unloaded turf tires and no other weight.  I plan to make a counterweight to go on the 3 pt., but haven't gotten around to it yet.
I haven't used the 3 pt. yet, but plan to get a 4 ft. brush hog to mow my fields a couple times a year.  A guy that I work with wants to sell his 4 ft. Howse brush hog that he bought new this year to get a bigger one.  Does anybody have any experience with this brand, and should I pursue it?
